If you play prime-time, on the first day after maintenance or the last day until maintenance, you get a ton of teams wanting to get their games in.
Assuming you don't remake your team, to start at 1500 again, you'll eventually rise or fall to your true rating.
At that point, teams will be about as good as you are, and the matches should be close.

If you play at any other time, there won't be enough teams on at once, and you'll be matched against the closest rated team, which might be significantly different rating from your team.

In the end, for most of us, its just about getting the points.
Be sure to play every week, even if you just queue and don't join. The points will add up.
Down the road, your gear improves and you'll need to worry about whatever rating, to spend your points but that's later, not now.
